Hi, Marc,
Here’s the KM code for the “Time to Save” idiot warning.
Or were you asking to see my whole KM set? I don’t mind sharing that either, though a lot of folks would call it overkill — there are about 110 of them. I do enough writing that it was worth the time investment to create them; I figure I’ve long since recovered the time.
I have keystrokes, for example, that do every dynamic combination I could think of, from single dynamics to any combination of dynamics linked by crescendos or decrescendos, or even just a cresc. or decresc. to or from any given dynamic. 57 shortcuts just for the dynamics.
There are nine shortcuts for some common time signatures — one keystroke for each of the common x/4 and x/8 meters.
And then there are just a whole lot of miscellaneous ones, like a keystroke for an arpeggio marking or a glissando. (The first time I wrote a major harp part, those became immediately important!)
And of course the humorous part of it is that between all my KM shortcuts and the keystroke shortcuts I’ve added through Dorico preferences, I can’t usually remember them all. So three of my KM keystroke shortcuts are to show Reminder Windows listing (more or less by subject group) all kinds of info, including keystrokes, how-to reminders, even some unusual instrumental transpositions (I do a lot of orchestral transcribing); in short, anything that I tend to forget. My rule of thumb is, if I’ve had to look it up twice, it goes into one of the reminder files.
Having said all that, I live in deadly fear that my “system,” such as it is, will become so overloaded that I’ll have to create Reminder Windows telling me in which Reminder Window the particular thing I’m looking for resides! 
Anyway, I’ve attached the “Save now, Idiot!” warning, but if you’d like my whole KM file, I’m happy to share; just let me know.
That applies to anyone out there with Keyboard Maestro, btw; I’m happy to share my shortcut file.
